COOLING ATTACHMENT FOR GAS AND OTHER MACHINES.

SPECIFICATION forming part of Letters Patent No. 310,616, dated January 13, 1885. Application filed October 13, 1884. (No model.)

To all whom it may concern.-

Beit' known that I, JOHN RING, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improve ment in Cooling Attachments for Gas and full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification, and in which- Figure 1 is a side elevation of a gas-pump with my attachment applied. Fig. 2 is a vertical section of the stufling-box of the machine andthe oil-chamber of my attachment. Fig. 3 illustrates a modification.-

My present invention relates to an apparatus for cooling the piston-rods of gas pumps or machines; and it consists in features of novter fully described, and pointed out in the claims.

I have illustrated my improvement on the. machine shown and described in Letters Patent of the United States N 0. 267,653, issued to me November'l4, 1882 but it may be applied to' all kinds ofgas machines or pumps.

Referring to the drawings, A represents the pump, B the stufling-box, G the pistonrod, and. D the return or condenser pipe, all of which are shown and described in my patent mentioned, and all of mon to gasmachines. Surrounding the piston, at the outer end of the stuffing-box, isa cylinder or box, I, forming an oil-chamber, preferably connected by a gland, L, as shown.

M represents an oil-tank connected to the oil chamber or box J I by a circulatingpipe, N. The tank M, chamber J, and pipe N being filled wit-h oil, a circulation in the direction indicated by the arrows will be caused by the oil being heated in the chamber by the hot piston-rod. After leaving the chamber, and beforereaehing it again, the oil is cooled. by some suitablemeans. My preferred means is to coil the pipe N around the return-pipe D,which is kept very cold by the return gas, and. will thoroughly chill the oil as it passes through the coil. Another means for-cooling the oil is shown in Fig. 3,where" a box, 0,. for containing cooling-liquid or ice surrounds any sediment that might settle therein.

which are comthe tank M. The pipe N is provided with.

. valves or cocks P,which may be closed if it is desired at any time to clean the chamber g tof e tank, chamber, and pipe must'be keptwell filled with oil, in order to keep .up the circulation, and the oil may be supplied through a funnel, T. By my improved attachment thepiston-rod is kept cool, and at the same timewel1lubricated,mnch more effectually than by pouring eoldwater over it, as is the practice.

with these gas-machines, which not only' poorly serves to cool it, but also causes it to wear away rapidly, owing to the sediment and lime being deposited thereon from the water, which is frequently a cause of breakage, and, moreover, the lime and sediment are carried by the piston into the and destroying it. The tank M could be dispensed with, thoughl prefer to use it. A flexible connection can be made between the pipe N and box I, to allow the endwise movement of the box when the gland L is tightened or loosened. This flexible connection can be made by meansof short pieces of hose lined with some substance impervious to oil.

packing, tearing- My invention can be applied to advantage to all kinds of fitst-running machinery where pistons or journals are liable to become heated.

I claim as myinvention- 1. In combination with a gas or'other machine, the oil chamber, tank, and circulatingpipe, .the chamber surrounding the piston-rod of the machine, substantially as set forth.

2. In combination with a gas or other machine, an oil-chamber surrounding the pistonrod of the machine, and a circulating-pipe, with means for cooling the oil as itpasses through the pipe, substantially as and for the purpose set forth.

3. In combination with a gas or other machine, an oil chamber, tank, and circulatingpipe, the chamber surrounding the piston-rod and the pipe being coiled around the returnpipe of the machine, substantially as and for the purposeset forth.

JOHN RING.
